Combine nested media queries on compilation

[melat0nin]

Would it be possible to combine nested MQs on compilation to reduce filesize? At the moment scss-php (and I believe SASS in general) will output this:

@media (max-width: 767px) {
  header #logo {
    background: black; } }
@media (max-width: 767px) {
  header {
    width: 90%; } }

...instead of:

@media (max-width: 767px) {
  header #logo {
    background: black; } 
  header {
    width: 90%; } }

The duplication of code can make for large files if there's a lot of SASS.

Love the idea! I can't say when either scssphp or sass, in general, will have a global optimizer though.

Closing this under the sass community guidelines (until there's a reference implementation in ruby sass).
